UP status incorrectly given to anything in 2.0-alpha.2

[johrstrom]

What did you do?
Misconfigured Prometheus 2.0-aplha.2 such that it attempts to scrape a host does not exist. It was then marked as UP even though it should not have been.

What did you expect to see?
Items marked appropriately in the /status page (UP iff they're up and DOWN iff they're down)

What did you see instead? Under which circumstances?
Everything is marked as UP regardless of whether that's actually true or not. You can replicate easily by using a host name that isn't reachable. You can use the config below.

• Prometheus version:

prometheus, version 2.0.0-alpha.2 (branch: HEAD, revision: ab0ce4a)
build user: jeff@localhost.localdomain
build date: 20170525-21:21:28
go version: go1.8

• Prometheus configuration file:

scrape_configs:
- job_name: "up-test"
  static_configs:
  - targets: ['does.not.exist']
